Around 100 million years ago, there was an enormous explosion of methane that made its way up into Earth’s atmosphere, which, along with a few powerful volcanic eruptions, helped bring about a profoundly hot climate. Now, it appears that researchers wandering through the Arctic...]]> Wed, 26 Apr 2017 00:13:39 -0400 Invitation to survey on key priorities for polar research EU-PolarNet and a group of 50 polar experts and stakeholders are working together to develop a set of polar white papers. These white papers will provide a state of the art for a range of societal relevant polar issues and outline possible approaches on how to address these. They now invite...]]> Fri, 21 Apr 2017 18:22:38 -0400 Arctic river ice deposits rapidly disappearing

Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.

River icings form when Arctic groundwater reaches the surface and solidifies on top of frozen rivers. They grow...]]> Wed, 19 Apr 2017 22:18:55 -0400 Methane Seeps in the Canadian High Arctic Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, discovered an astounding number of...]]> Wed, 19 Apr 2017 22:13:55 -0400 Earth Day Polar "Tweetstorm" The US National Committee of the Association of Polar Early Career Scientists (USAPECS) is organizing a "Tweetstorm" event to celebrate Earth Day on April 22nd. The basic gist of the event is that polar scientists who use Twitter should tweet blurbs about why their research is important (with...]]> Wed, 12 Apr 2017 17:58:14 -0400 Call for Nominations for Polar Research Board The National Academies of Sciences, Engineering, and Medicine seek nominations of potential new Polar Research Board (PRB) members with expertise and practical experience across all areas of polar science (both physical and social sciences), engineering, and policy. The goal is to have a...]]> Tue, 11 Apr 2017 20:07:56 -0400 The Arctic Ocean Is Becoming More Like the Atlantic Ocean

The Arctic is undergoing an astonishingly rapid transition as climate change overwhelms the region.

New research sheds light on the latest example of the changes afoot, showing that parts of the Arctic Ocean are becoming more like the Atlantic. Warm waters are streaming...]]> Tue, 11 Apr 2017 20:05:52 -0400 Scientists uncover isotopic fingerprint of N2O emissions from Arctic tundra

A new study from the University of Eastern Finland presents, for the first time, the isotopic fingerprint of nitrous oxide produced by Arctic soils. The finding opens new avenues for predicting future trends in atmospheric nitrous oxide as well as in identifying climate change...]]> Tue, 11 Apr 2017 19:52:28 -0400 Climate change could destroy far more of the Arctic's frozen soil than we expected

Climate change could cause another 4 million square kilometers, or about 1.5 million square miles, of permafrost to disappear with every additional degree Celsius, or 1.8 degrees Fahrenheit, of warming, a new study suggests.

The estimate, which was published Monday in the...]]> Tue, 11 Apr 2017 19:44:59 -0400 Survey Input Requested: Summit Station Science Summit Organizing Committee This survey will be used to assess the major science questions investigated at Summit Station, Greenland.

Vast Arctic landscapes may appear to be desolate, barren places, but take a look through a microscope and you'll see thriving ecosystems. The top few meters of ice are home to an estimated hundred million billion trillion (or 10 to the power of 29)...]]> Fri, 07 Apr 2017 17:40:58 -0400 Call for Arctic Data Center Working Group Proposals The Arctic Data Center, in collaboration with the National Center for Ecological Analysis and Synthesis (NCEAS), announces a call for working group proposals.
